New pool owner, completed in July of last year. My intellichem worked beautifully all last year, but this spring, I started noticing that I was reaching the ORP Limits on a daily occurrence, so I just started upping the limits and dosage, to the point now that I'm at 15 doses of 1/3 gallon (42 oz) per dose, with a mix time of 45 minutes. (Set it at this point so that it would essentially be 5 gallons (more than my container 4 gallons) and I could see if the pump was actually dosing 5 gallons, or if the software just assumed it was dosing that amount. And have deduced that in fact, my stenner pump is NOT putting out that much chemical in the period of one cycle day. At most, I've seen it dispense about a gallon before the ORP limit light comes on, and that light sometimes comes on 2-3 hours after I have manually cleared the limit. (Confusing). The limit is set to naturally clear at Power-On, and the Intellichem does not stay powered on the entire day, it only has power when the pool is in filter mode. (10:00 am to 8:00pm).
Things I've done to correct:
I thought perhaps my filter pressures were too high- the stenner pump is 25PSI, my filter was running about 20, so I thought cleaning my cartridge filter might help. It did lower the PSI to about 14, but that did not clear my issue.
I read where the pump tubes need to be replaced annually, so I change the ORP pump tube. Still reaching the ORP limit.
What's a mystery, is that as long I keep resetting the limit, the intellichem can still keep my pool at my ORP set point (700). Water is beautiful, and my manual checks of the pool all show in range, the Intellichem is actually dosing the pool with Chlorine correctly, but something is triggering the limit.
I've called Pentair support, and they will dispatch technician for warranty (which is the installing company), and the technician has been honest with me, saying that his company has only installed one other Intellichem system, and he says I probably know more about this setup than he does. Just trying to see if someone has some idea of what could be causing this limit to be invoked prematurely. Is this a hardware issue, software issue, or just plain old User Error?
